I am playing a POTD solo chanter/bleak walker pala. I tried rerolling my character at level 7 (reseting talents/levels/skill points whatever you call it), and i lost my level 1 phrase which i got during character creation. It was the damage overtime one that deals 2 raw damage and heals you for 2 health. I did not lose the summon skeletons from creation, just the phrase.

I want to buy into the beta but since i bought the game directly from steam I cannot do it, is there a particular reason for this? What can I do to get into the beta now that I have the game on steam? Yes, I am aware that the game is 1 month away and the beta is short, but I pre-purchased solely for the reason that I could kill time on the beta.
